Hello Randall,
Basically, the previous versions of the control (including the one that you have), could style only the textboxes and the buttons used in the login control - to do that, just make sure that EnableRoundedCorners is set to true and the decorator is set to style textboxes and buttons.
To be able to fully style the login control however (like shown in the demo), you need to upgrade to a more recent version of the controls.
